Aconstruction, including the springs padding and the section of covering material just referred to extend over the arch supporting extension 11i. rlfhe meeting edges l through the cover atthe front edge of the.

device, and preferably at the forward end of the ribs 12, are openings 20, which serve as outlets for the air-space between plates 110 and 13.

The device thus constructed is placed in the rear portion of the boot or shoe directly upon the insole with the arch-support lying immediately: against the lower inner portion of the shoe-upper (see Fig. 1). Thus whenV the foot is placed in the shoe, the arch or instep 'of the foot is supported by the extension 14: andthe entire heel-portion of the foot is yieldingly supported by the rear portion of the device, which, by virtue of Cts escribed, serves as apad or cushion. While the wearer of the shoe to which the device is applied is walking, the upper rear portion of the pad will be forced toward the lower rear portion, during which action the spring 17 willbe compressed andthe rear portion ot' spring 15 will be moved downwardly;

such action necessarily expels the air from the space between the upper and lower parts of the device, such air finding exit'in thel spaces between the forward portions of plates 10 and 1:3 and through the openings 20. When the foot is lifted, as in taking a step, the springs within the device act to move the rear portions of the plates 10 and 13 apart, which action draws air intothe air-space within the device throu h open'- ings 20. Thus it will be seen thatV t e device while in action performs the functions of a bellows or an air-pump, with the result that a circulation of air is producedin the lower portion ot' the shoe, consequently. tending to reduce, by evaporation, perspiration of the foot and maintaining the support and pad in a' comparatively dry condition. Inasmuch as the extension 14: istormed on top plate 13 and said top-plate isl yieldingly forced upward under the influence ofsprmgs 15 and 17,'said extension will be yieldingly maintained with a certain degree of upward pressure in proper position to support the Y arch or instep.

The form of device illustrated in Figs. 6 to 9 inclusive is intended for use as aventi-v lating pad only, and this form of device is practically the same in construction as the combined pad and arch support herein 'described, with the exception that theunder lying layer or leather 11, the top pad 18, and the arch-supporting extension are dispensed with.

. A'device of my improved construction is .comparatively simple, can be easily and cheaply manufactured, can be readily positioned within or removed from a shoe, and

in service provides an effective Ventilating. pad for the shoe, as well as forming a selfadjusting support for the arch or instep of the foot.

It will be readily. understood that minor changes-in the size, form, and construction.

of my improved device may be -made and substituted forthose herein shown `and described without Ideparting vfromlthe nature and spirit of my invention. 'y

'Havingthus described my invention, what I claim and desire to secure by Letters Patent is:

V1. In a device of the class described, a pair of plates spaced apart and secured to each other near'one end,.their other ends being free, .a spring interposed between the i free ends of said plates, and a cover inclos-v ing said plates, there 'being openings in said cover communicating with the space; between the attached ends of said plates.

2. In a device'of the class described, a pair of plates secured to each other near one end, their other ends being free, ribs formed on one ofthe plates, which ribs serve as spacing means between the connected ends of said plates, a spring interposed between the free ends of said plates, and a iiexible member inclosing said plates, there being openings formed in said'inclosing member communicating withthe space between the connected ends of the plates.

3. In adevice of the class described, a pair of plates spaced apart and securedto each other near one'end, their other ends being free, a springinterposed between the freel ends, of said plates, the' upper plate having an outwardly projecting lupwardly curved extension on one side, and a fiexible member inclosing said plate andsaid eXtension, there being openings 1n sald coverlng member which'eommunicat'e with the space between the attached ends of said lolates.

4'. In a device of the class -des zribed, a. pair of 'plates spaced' apart and secured to each other .near one end, their other ends being free,a spring interposed betweenthe free ends of saidplates', alayerof iexiblc material 'beneath-the lower plate the upper g.

plate having an 'outwardly projecting upwardly curved extension'on oneside, andaflexible member inclosing saidplates ,and4 '120 Vthe parts carried thereby, there being' 'openings formed in said inclosing member-"coma municating with the space between'the connected ends of the-plates. l

. In testimony whereof, I have attachedv my name to this-speciication.
